Peter Lewis Bailey N.O. in his capacity as Liquidator of United Merchant Bank of Zimbabwe Ltd v Edmore Tapera Mazambani

The plaintiff, as liquidator of United Merchant Bank (UMB), sued the defendant farmer for payment of $1,336,371.12, being the balance of a loan granted on 29 September 1997. The defendant admitted the initial indebtedness but claimed he had discharged his liability in full by paying through a stop order facility registered with Boka Tobacco Auction Floors (BTAF), which he alleged was the bank's agent. The loan facility letter required security including a stop-order against the defendant's tobacco crop. The defendant claimed he delivered tobacco between April and August 1998 to BTAF, which would deduct amounts and remit them to the bank. The last tobacco sales sheet (13 August 1998) reflected a deduction of $38,702.12, which the defendant disputed, claiming he had fully discharged his indebtedness. The defendant was unable to produce comprehensive proof of delivery or payment of tobacco sufficient to cover the loan amount.

• Whether Boka Tobacco Auction Floors acted as an agent of the bank or as an agent of the defendant
• Whether the defendant had discharged his indebtedness to the bank in full through deliveries to BTAF
• Whether the registration of a stop order against the defendant's tobacco crop was a precondition to the loan that created an implied agency relationship
• Whether agency by estoppel was established on the facts

Judgment entered in favor of the plaintiff. The defendant was ordered to pay: (1) $1,338,371.12 together with interest at 27% per annum from 1 February 2000 to date of payment in full, capitalized at the end of each calendar month; and (2) costs of suit.

The binding legal principles established are: (1) A provision requiring a stop order as security for a loan does not, without more, create an implied agency relationship between the creditor bank and the auction floor where the stop order operates; (2) Agency by estoppel requires proof that the principal's conduct reasonably misled another party into believing a third person had authority to act, and that the party entered into a transaction to their prejudice in reliance on that belief; (3) A defendant claiming to have discharged a debt bears the burden of proving both the delivery of goods as payment and that the value was sufficient to cover the indebtedness; (4) Where a party undertakes to produce specific evidence at pre-trial conference but fails to do so at trial without explanation, this failure is fatal to their case on that issue.

The court observed that if the defendant had shown that on a number of occasions the bank had allowed BTAF to recover money from him but only failed on one occasion to pass it on to the bank, then the bank could have been estopped from denying that the money was paid to its agent. The court also noted that even if one were generous enough to accept that a provision for security is a condition for the grant of a loan, this alone would not be sufficient to imply that the bank appointed BTAF as its agent. The court made reference to the general principle that contracts of agency may be entered into not only by express language (written or oral) but also by conduct.

This case establishes important principles regarding the burden of proof in defending against debt claims, particularly where payment through third parties is alleged. It clarifies that security provisions in loan agreements do not automatically create agency relationships. The judgment reinforces the distinction between actual agency, implied agency, and agency by estoppel, requiring clear proof of conduct that would mislead a party to their prejudice. It also demonstrates the consequences of failing to produce evidence promised at pre-trial conference, and the strict requirements for proving discharge of debt where payment through intermediaries is claimed.
